mpc8308rdb: add support for eSDHC MMC controller
Add support for the onboard eSDHC MMC controller. The hardware on the MPC8308RDB has the following errata: - ESDHC111: manual asynchronous CMD12 is broken - DMA is broken (PIO works) Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu> [added include fsl_esdhc header to prevent implicit declarations of fsl_esdhc_mmc_init() and fdt_fixup_esdhc()] Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
